STOVE-GRATE.

SLDECEPECATON forming part of Letters Patent No. 329,868, dated November 3, 1885.

Application filed May 31,1884. Serial No. 133,346. (No model.)

To @ZZ whom it 71mg/ concern:

Be it known that I, HENRY H. VHEELER, a citizen of the United States, residing at Tifiin, in the county of Seneca and State of Ohio, have invented certain new and useful Improvements in Stove-Grates, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention is an improvement in grates, ro and is designed to produce a grate that, with simple mechanism, shall have a reciprocatory and a dumping movement; also, provide a means whereby the grate may be prevented from dumping when it is at rest.

In describing the device reference will be had to the annexed drawings, in which Fig. ure l represents a plan view of the grate, its surroundings being in section; Fig. 2, a longitudinal section through the grate, showing 2o one of the grate-bars and its connections; Fig. 3, a detail view of the connecting-yoke, and Fig. et a detail section showing the retaininglug.

In the gures are shown two grate-bars, A

and B, respectively, though the number may vary with the dimensions of the grate. These bars are constructed of a central web and transverse lugs, as shown, the bar B having at one end and on one side a transverse lug 3o of larger size than the others, which lug is provided with a slot on its under side. The lug is indicated on the drawings by the letter C, and the slot by D. The bar A is formed at one end into a shaft, D, which rests in a suitable recess or bearing, E, in the framework surrounding the grate proper, and at the other end with an extended shaft passing through the frame and terminating in a head, F, which is provided with a slot, G, for the 4o insertion of an operating-lever. The webbing which connects the transverse lugs on the grate-bar is shorter than the grate-frame, and thereby allows the said grate-bars suf- .iicient room to have a certain longitudinal movement necessary in shaking the grate. The slots or bearings E are recessed into the grate-frame sufficiently to allow the said longitudinal movement ofthe grate-bars. These recesses are provided with slots H, leading 5o down into the ash-pan, so that any ashes that may nd their way into the said recesses will be immediately discharged into the said ashpan, thus relieving the bearings from all obstructions.

Pivotally connected to the slot D' in the 55 grate-bar B is a yoke, I, the connection being made by a pin, K, which passes through one arm of the yoke and into the sides of the slot. This yoke passes under the grate-bar A and connects with it (the said bar) between two of the lugs by means of a pin similar to the pin K. The yoke has a nose, L, which projects beyond the said connection with the grate-bar and rests normally in a slot, M, in the grate-frame. This slot is long enough to 6 5 allow the yoke to travel with the grate-barA in its longitudinal movement. The yoke at its center N is extended downward somewhat and has a beveled under surface. In the normal position of the grate this surface is nearly level, as is evident. The center N ofthe yoke rests in a bracket, O, preferably formed integral with the grate-frame. It will be seen that when the bar A is given longitudinal movement by means of a shaker7 inserted 75 in the shaft-head F, the end of the yoke secured therein will move also, (the pin having a slight play in its seating) which will cause the other bar to move in the opposite direction, the bracket O operating as a pivotal point for the yoke. rIhus the grate is shaken or given a reciprocatory movement.

Vhen it is desired to dump the grate, the lever is operated to turn the bar A on its shafts. The end of the yoke connected thereto will be elevated and cause the other end, secured to the bar B, to be depressed, carrying the said bar with it, the same operation being performed through a series of bars.

To prevent any unintentional dumping of the grate, a lug is cast on the frame at P, against which the web of the grate-bar A engages when the said bar is moved snug up to the frame.

When several bars are used in the grate, they are all connected by yokes and operated by one lever, as in the drawings. The lug P may also be multiplied.

Having described the device, what I claim 1s- 1. In combination with a series of grate- IOO bars, a yoke pivotally connected therewith and provided with a nose or projection normally resting in a slot in the grate-frame, substantially as and for the purpose specified.

2. The combination, with a series of gratebars, of a yoke pivotally connected therewith and provided with an extended central portion having a beveled bearing-surface, and a 'bracket depending from the grate-frame, substantially as and for the purpose specified.

3. In combination with a series of gratebars, a frame therefor in which the said bars have extended hearings, the frame having on it lugs, against which Vthe Web of the bars normally rests, substantially as and for the purpose specified.
